1results about How to "Improve error precision" patented technology

The application provides a cooperative control method for a multi-axle heavy off-road vehicle height-adjustable independent suspension, and belongs to the technical field of vehicle suspension control, and the method comprises the following steps: S1, scenario-based hierarchical setting of a target vehicle height; S2, synchronous acquisition of a vehicle body state and load pressure and difference calculation; S3, load adaptive single pendulum wave-cuckoo cooperative motion planning; S4, pilot pressure synchronous output control based on load grading; S5, multi-channel flow decoupling proportional valve dynamic control; S6, chaotic-single pendulum wave fusion adaptive sliding mode closed-loop feedback; S7, double-verification system locking and unloading control. The application solves the technical pain points of complex structure, poor synchronism, insufficient stability, and low precision in the height adjustment of the existing multi-axle heavy off-road vehicle oil gas spring suspension, and finally realizes the significant improvement of the passing capacity and handling stability performance of the multi-axle heavy off-road vehicle in the off-road scenes such as muddy roads, rocky roads, and sand dune roads, and meets the driving requirements in complex road conditions.
